What is the most interesting thing you have learned in science?

First placeThe most interesting thing I’ve learned in science is probably the three states of matter. The three states of matter show how something can change three times and still have the same molecules. In my class, we did it with water. First, it is a solid. When it is solid, it is ice. Ice has volume and has a shape. Ice has three atoms per molecule — two hydrogen and one oxygen. To be ice, the temperature has to be 32 degrees or below. The next state of water is liquid. When ice turns to liquid, it becomes water. Water does have volume too, but it has no shape. Whatever container you put it in, it turns to that shape. When it is a liquid, it still has two hydrogen atoms and one oxygen atom. The last state of water is gas. When it is gas, it has no shape or volume because it doesn’t take up space. Even though it is now gas, it still has the same molecules. Those are the three states of water. Leah RoysdonFifth gradeLive Oak Elementary

Second placeThe most interesting thing I have done in science was the food chain. The food chain is sad, but also interesting. First, you have a cute worm. A bird eats this worm. Then, the bird gets stalked by a cat. Right when the bird is not paying attention, the cat pounces on its prey. Next, the cat walks around happy with its catch for the day. Then, the coyote strikes the cat. Later, the coyote dies, and the bacteria eat the coyote. That is the food chain.Will ChambersFifth gradeLive Oak Elementary

Third placeThis year in science, I am learning about bones and joints. It is fun! Bone marrow is a connective tissue that provides red and white blood cells. Red blood cells carry oxygen through the body. White blood cells fight germs. Bones meet at the joints where they are attached together and to muscles. On each side of a joint, muscles are attached to bone by tendons. Tendons are tough bands of connective tissue. Bones are attached together by ligaments, bands of connective tissue that hold the skeleton together. A neuron is a specialized cell that can receive signals and transmit them to other neurons. Receptors are the nerve cells that detect conditions in the body’s environment. Colin McKinneyFifth gradeLive Oak Elementary

I think the most interesting thing I have learned about in science is rocks and what they are called. I liked it because sometimes we would talk about an interesting rock, and I would go home to look for it after school. I also liked learning about how hard they are. Diamonds are the hardest kind of rock. My favorite rock I learned about was granite because I found out all the things it’s used for, like tables. That was the most interesting thing I have learned about in science. Jacob ManlyFifth gradeLive Oak Elementary

In fourth grade, I learned about many things, but my favorite subject was science. What I learned in science was the food chain. Let’s say a fish is swimming free in the ocean, and a sea lion comes charging for the fish and eats it. Then, a killer whale stalks the sea lion for a while and then shoots for the creature and swallows it whole. Yes, the food chain is sad. But if there was no such thing as the food chain, we all would not be here. Neither would the animals.Haleb QuesadaFifth gradeLive Oak Elementary

The most interesting thing that I learned in science was about the food chain. The plant at the bottom of the food chain gets eaten by an animal. It doesn’t always have to be plants and animals. It could just be a piece of cheese, a mouse, a snake, a bird and a human. So it could be like this; a mouse sees a piece of cheese on the ground and starts munching on it. Then, a snake slithers silently toward the defenseless little mouse and eats it up. After that, the eagle spies the snake and eats the snake. Finally, the human shoots the bird and gobbles the bird up. And that is the food chain. Jairo FrancoFifth gradeLive Oak Elementary

The most interesting thing I have learned in science is the body system. The body system has lots of systems, like the digestive system. The digestive system works like this: first, you eat food and it goes down the esophagus. Then it goes to the stomach. It then goes to the small intestine — which is actually 23 feet long — to go to the large intestine and the villi that gets the nutrition. Then it goes out of your body and that is all I have to say.Isabella GonzalesFifth gradeLive Oak Elementary

The most interesting thing I learned in science was volume. Volume is where you can measure square things by the using this equation: volume = length x width x height. But if it is not squared, you can use a graduated cylinder and fill it with liquid up to a number of your choice. Then you drop in your matter, and the liquid will rise and you can tell by the numbers the liquid rises to. Then you subtract the number it rises to and you get the volume of your matter. If you don’t have a graduated cylinder, you can use a measuring cup. Remember to use more liquid to fill it up because it is wider then a graduated cylinder.

The most interesting thing I learned about in science is the atmosphere. It is interesting because the atmosphere has many layers. We have the troposphere where most planes fly. The stratosphere is a layer where most of our weather is in. The mesosphere air temperature decreases with height. The mesosphere is a cold layer. The thermosphere is a hot layer. Temperature highs in the thermosphere can reach into thousands of degrees celsius. The atmosphere is like a thin blanket that covers the earth from the sun. If we had no atmosphere, it would be very hot on earth.Alex CastilloFifth gradeLive Oak Elementary

I think the most interesting subject in science is the atmosphere. I like the atmosphere because I learned a lot of new stuff. The atmosphere is a thin blanket that covers the whole earth. If we didn’t have the atmosphere blocking 50 percent of the sun’s heat, we would all go bye-bye. The atmosphere is really cool. It’s a blanket covering the world. Only 5 percent of the sun’s rays bounce back in the air. Just imagine, 95 percent of sun coming straight down. That 95 percent could never happen because we have the atmosphere. That was the most interesting subject for me because I think it is very cool.Blake KuykendallFifth gradeLive Oak Elementary
